"""
The most atomic way to train and inference a GPT LLM in pure, dependency-free Python.
Differences from GPT-2 are minor: rmsnorm instead of layer norm, no biases, square ReLU instead of GeLU nonlinearity, no weight tying.
The contents of this file is everything algorithmically needed to train a GPT. Everything else is just efficiency.

Create a 16bit R5G6B5 raw image for embedded displays.

  • Import your image or create image with GIMP.

  • Export as bmp -> advanced options -> 16bit

  • Then to get the raw bytes run tail -c $bytes image.bmp > image.raw where $bytes is w * h * 2 of the image. This removes the BMP header.

Simple Atomic File Locking in Linux

Simple Atomic File Locking in Linux

If you have access to a traditional programming language, there are many methods1 to use2 locks in linux3. However, we don't necessarily have access to those methods within a shell script. In addition, using locks over different kinds of filesystems (such as NFS) can also have inconsistencies and bugs.

What if you just want a very simple form of locking that works on all filesystems? The answer is Maildir locking. The way Qmail / Maildir works is specific to mail files, so I'll break it down in a more general way below. You also don't have to strictly follow this method; the general idea can be modified.
